. lMPROVEMENTlN WAGON-SPRINGS.

Specification formingpart of Letters Patent No; 177,701, dated May 23, 1876; application filed March 17, 1876.

To all whom it may concern.-

Be it known that I, CONRAD EMBERGER, of Port Richmond, Staten Island, in the State of New York, have'invented a new and useful Improvement in Springs for Carriages or Buggy, of which the following is a specification: I

This invention consists in the manner of strengthening the Wooden springs used under a bnggyor box wagon, by the application of a steel plate in the body of said wooden bar. or spring, said steel plate being inclosed in linen or canvas, which istirmly secured through lime or glue together'and to the wood.

In the accompanying drawing, Figure I represents a longitudinal view of an elastic wooden spring, partly in section, embodying my invention. Fig. II is an enlarged (:rosssection of the same. I l

A is an elastic wooden springwhich eonnects the axles, and upon which the bed or body of the wagon or buggy is supported in the usual manner. This wooden spring is provided with a deep recess, open on the under side, into which a steel spring-plate B is placed, as well as a piece of wood 0, to fill up the recess or cavity flush with the under side of the Wooden spring A. The steel spring-plate B is inclosed perfectly tight in a piece of linen, or other suitable textile cloth, 8, whose ends are firmly attached togetherat the lower side of the'spring-plate by being cavity in ,the under side of the wooden spring A, which is made of such dimensions that these above mentioned parts will fill said cavit'y tightly, and said cloth a will then, in consequence of its glue covering, firmly adhere to the sides of the cavity, and consequently to the wooden spring A, thus connecting the steel plate B and wooden piece 0 firmly with the body of the wooden spring A.

By this arrangement the steel plate is protected from every detrimental effect of the atmosphere or moisture, and a stronger and more powerful spring is obtained, and while the steel plate is, throughout its entire length,

firmly and solidly attached to the wooden spring A, all bolts, clamps, or other contrivances to attach the steel plate to the Wooden spring, and which are very apt to weaken the steel plate are dispensed with.

I am aware that wooden springs, as Well as steel plates, either single or combined have been used for this purpose; and do therefor not claim the same or either of them; but

. What I claim as my invention, and desire to secure by Letters Patent, is-

Theherein-described spring, consisting of the combination of an elastic wooden spring, A, with a steel plate B, when said steel plate B, placed in a cavity at the under side of said wooden spring or bar, is inclo'sed in a linen cloth, 8, or its equivalent, to which the bottom wooden piece 0 is firmly attached, and. these parts surrounded with another linen' or other cloth, a, attached to the same, and to the inside of the cavity in the woodenspring A, by means of glue or other suitable paste, substantially in the manner andfor the purpose herein set forth.
